COILING-MACHINE Specification of Letters Patent.

Patented Oct. 1, 1907.

To all whom it may concern.-

Be it known that-I, MARCELLUS O. LOVEJOY, a citizen of the UnitedStates, residing at Portland, in the county of Cumberland and State ofMaine, have invented an Improvement in Coiling-Machines; and I herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to machines or tools for producing spirals or coilsfrom continuous thin strips or ribbons-of the softer metals and theiralloys and it is my purpose to provide a machine which will effect thisend in the most economical and expeditious manner.

Myinvention consists in a shaft, a former provided with a recess in theend adapted to receive the material and form the successive rings of thecoil or spiral and also with an opening to receive the shaft, meanswhereby either the former or the shaft may be prevented from revolvingwhile the other revolves, and suitable means for giving the material therequired tension as it enters the device. The shape of the recess varieswith the shape of the strip or ribbon of metal to be coiled; if a ribbonof flat metal, the face of the recess is plain, if V-shaped or circular,the face of the recess is shaped-accordingly.

In the mechanism in which I have embodied my invention and which ishereinafter described, I have provided for the revolution of the shaft.In the description thereof reference is madeto the drawings in whichFigure 1 is a side elevation of shaft and former; Fig. 2 is an end viewof the front of the former; Fig. 3 is a vertical longitudinal section ofthe former; Fig. 4 is an end view of the rear of the former and holdingdevice; Fig. 5 is a side elevation of the shaft and a modification ofthe former; Fig. 6 is an end view of the front of a modification of theformer; Fig. 7 is a vertical longitudinal section of the former shown inFig. 6; Fig. 8 is an end view of a further modified form of former; Fig.9 is a side elevation of the former shown in Fig. 8; Fig. 10 is a sideelevation of the former with the feed or tension device attached, andFig. 11 is a section on the line x r, Fig. 10, looking in the directionof the arrows.

The shaft a is of ordinary construction journaled preferably only at theend where power is applied. The former b has a longitudinal circularopening a sufiiciently large to permit the shaft to revolve within it.The front end of the former b is provided with a recess d concentricwith the center of the opening a, the outer side of the recess beingformed by the circular shoulder e from which the recess extends inwardlyto the opening 0. The width of the recess d should be equal to the widthof the material to be treated and its face conforms to the shape of suchmaterial as already stated: see Figs. 5, 6 and 7.

At some convenient point a diagonal slot is made in the wall 6 and thesurface of the recess within the slot in the wall grooved, as showninFigs. 1, 2, 5, and 6. The groove when the face of the recess is plainor fiat as shown in Figs. 1 and 2 differs somewhat from the groove whichis made use of when the surface of the recess is raised as shown inFigs. 5 and 6. In the former case the groove is made by removing theface of the recess within the slot in the walls to an extent equal tothe thickness of the material to be treated, while in the latter casethe raised face of the recess is cut diagonally by the groove and theraised portion of the face on one side of the recess slightly beveled asshown in Fig. 5. The slot in the wall and groove thus made constitutethe opening indicated by f in the drawing.

Various means may be used to hold the former from revolving while leftfree to slide upon the shaft. The means which I have adopted, but towhich I do not confine myself, are shown in Fig. 4. An opening g is madein the side of the former 1) into which is inserted a rod h, which atits outer end is so secured as to prevent any revolution of the former,while at the same time movement longitudinally upon the shaft (1 ispermitted; as for example, and as shown in the drawing (-Fig. 4), theouter end may slide between two rods or bars k k placed parallel withthe shaft and to reduce friction the outer end of the rod h may beprovided with a pulley or sleeve 1.

Tension niay be provided by means of rollers m m having shoulders andbetween the shoulders surfaces which conform to the shape of the stripof metal to be coiled, that is, plain when the metal is fiat, V-shapedor semi-circular when the strips of metal are of those shapes,respectively. The rollers are journaled in a frame n which is fixed tothe side of the former; see Fig. 10. I

The operation of the device will be readily understood. A continuousstrip of metal of the required uniform shape, width and thickness havingbeen provided, it is carried between the rollers m m and the end thereofmay be secured in a slot 10 in the end of the shaft or otherwisetemporarily secured thereto by a clamp or other means or may be securedto the shaft by several turns around the shaft and then brought withinthe opening f in the wall of the former b. It is now pressed either byhand or by a suitable instrument within and against the face of therecess, the shaft revolving slowly. As the shaft revolves, the metal iscarried or drawn into the recess and is formed between the wall orshoulder e and the shaft a into a ring. After two or three rings of thecoil have been formed, their grip upon the shaft is such that theiropposition suffices to keep the other material, as it is fed in, withinand against the face of the recess 0, when the desired speed is giventhe shaft. As the coils are formed, the former gradually retracts untilthe shaft has been filled when the spiral already formed may be removedand the process repeated.

What I claim is:

1. In a device of the character described, the combination of a shaft, aformer adapted to slide upon said shaft, :1 track adjacent said shaft,and an anti-friction device carried by said former and engaging saidtrack, substantially as described.

In a device of the character described, the combination of a shaft, aformer adapted to slide upon said shaft and having a recess upon itsperiphery, an interlocking rod adapted to register with said recess, atrack adjacent said shaft, and an antifriction device whereby said rodmay slide freely With said former and lock it against rotation,substantially as described.

3. In a device of the character described, the combination with a shafthaving a slot therein adapted to temporarily hold the free end of thecoil, of a former provided with a longitudinal opening to receive saidshaft, and having a recess upon its periphery, an interlocking rod, oneend of which is adapted to enter said recess, a sleeve disposed upon theother end, and a pair of parallel bars adjacent said shaft, betweenwhich said sleeve on said rod is adapted to travel, substantially asdescribed.

4. In a device of the character described, the combina tion with aformer having a recess in its face, of means jacent said shaft, betweenwhich said sleeve on said rod is for feeding the material into saidrecess under tension, comprising a frame secured to said former, a pairof rollers mounted in said frame, having oppositely disposed flanges,whereby the material is fed through between the faces of said rollersand the flanges, substantially as described.

5. In a device of the character described, the combination with a formerhaving a recess in its face, or means for feeding the material into saidrecess under tension, comprising a frame secured to said former, a pairof rollers mounted in said frame having oppositely disposed flanges, andmeans for adjusting said rollers to regulate the tension, substantiallyas described.

6. In a device of; the character described, the combination of arotatable shaft having a central opening to receive said shaft, anannular l'cccss in one end extending from said central opening to theexterior wall, said wall having an opening to admit the material to saidannular recess and means whereby said former is prevented from revolvingwhile free to slide upon said shaft. substantially as described.

R, in a device for coiling a ribbon of solder upon its edge upon a shaftor mandrel, the combination with a rotatable shaft, of a former having acentral opening lo receive said shaft, and an annular recess in one endcx lendlng from said central opening to the exterior wall, said wallhaving an opening to admit the material to said recess. means forfeeding the material under tension, comprising' a pair ofsuitahly-mountcd rollers having oppositelyalisposed flanges, and meansfor adjusting said rollers to regulate the tension, substantially asdescribed.
